Hi! So I can't really help, - well at least I don't think I can. and I probably won't participate in this particular event because well, more than likely my timing will be off. I'll probably be at work or something TT_TT
As a note, that I literally just remembered - Hunger games style maps have been done before. Though normally it's a smaller map surrounded by a glass dome, and people can drop items to people below to "endorse" them.
The first thing I was going to suggest - would it be possible to have some players who will likely not be playing get "spectator" access to the map? Like with the Dynmap chat system - does it allow for restricting users view of specific worlds? (According to a github discussions I read it can actually!)
I just figured it'd be fun to watch and chat at the very least. I can see how chat might be an issue of telling users where other people are, but I'd hope we would be above that...
OOOH OOH Doesn't Minecraft now have a "spectator" mode? We could have people like me be in the world as a spectator! Since I probably can't be there to play due to my erratic schedule, I could drop in and watch from in game!
Now because I thought of other Minecraft hunger games, I came up with this idea:
Also, perhaps users who are spectators could have use of an "endorse" command which has a limited number of uses, and it's syntax could be like /endorse [Username] [shovel/sword/steak]
I think making the event interesting for spectators as well as players could be a good way to make sure the whole community is offered something.
